TEMPORARY BINDER.

' Specification of Letters Patent.

Patented May 14, 1912.

Application filed October 12, 1909. Serial No. 522,262.

To all whom it may concern:

Be it known that I, JOSEPH A. Moon, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Temporary Binders,-of'which 'the' following is a specification.

My inventionrelates particularly to temporary binders provided with means for preventing unauthorized removal of leaves therefrom, such as loose-leaf ledger-s; and

I my primary object is to provide ,in binders tremities with guides A of the type indicated improved means for operating and locking the binder through the medium of a single key.

The invention is illustrated in the preferred embodiment ther'eofin the accompanying drawing, in which.

F igure -1 represents a plan view of the operative portion of a loose-leaf binder with the key thereof detached; Fig. 2, a sectional view on an enlarged scale, the section being taken as indicated at line 2 of Fig. 1; Fig. 3, ,an enlarged horizontal sectional view taken as indicated at line 3 of Fig. 2; and Fig. 4, a broken perspective view showing the key-controlled and actuated barrel employed, a portion of the screw-rod employed, and a connecting member joining the barrel and screw-rod, the parts being shown disconnected.

In the construction illustrated, A, A rep resent the clamping members or jaws of a loose-leaf binder; A the back upon which said clamping members are transversely slidable, said back being provided at its ex A, telescopic binding-posts oining the edge portions of the clamping members A, A; A mechanismserving to open and close the binder, said mechanism including a right and left threaded screwrod A journaled on the binder-back; B, a key-controlled device throughv the medium of which the screw-rod A may be actuated; and B a connecting member joining the barrel of the device B to the screw A.

The binder may be of any approved construction. In the COIlStlUCtlOI1,SlIO\Vl1, the rod A is journaled on the back A and confined against longitudinal thrust at the point 1 in a well understood manner. Said rod extends longitudinally of the binderback practically from one end of the binder to the other. The mechanism A includes pairs of links 2 which have pivotal connection in the usual manner with'the clamping members and with nuts 3 mounted on the screw-rod A. It will be understood that when the rod A is rotated in one direction,

the binder-frame will be opened or ex panded; and when the red A is rotated in the opposite direction, the binder-frame will be contracted, the clamping members slidingltransversely with relationto the binder- The device B preferably comprises a block 4 which is screwed to the inner surface of the binder-back near one' .end thereof,

said block 4having a bore 5 in alinement with the adjacent end of the rod A; a keycontrolled and actuated barrel 6 extending I through the bore in the block 4 and provided with a circumferential groove 7 which receives a' pin 8 adaptedto prevent long-itudinal movement of the barrel with relation to the block 4; and key-retracted barrel-locking devices 9 connected with the block 4 and barrel 6. Each guide A comprises a removable guide-plate 10 which extends transversely across the end portion of the binder-back, being spaced with relation thereto to enable the flanges 11 of the clamping members to pass between them and the back. The block 4 is located be neath one of the plates 10, and issecur ed'between said plate and the back by means of screws 12.

The barrel 6 is rotatablein the bore 5, but normallylocked against rotation bythedvice 9. The barrel 6 is partially severed longitudinally by a key-receiving slot 13 adapted to receive a special key. There are a series of the locking devices 9, three of said devices being shown. Each device comprises a plunger 14 and a ball 15 received in a transverse bore 16 with which the key-barrel is provided; and a plunger 17 and spring 18 received in a registering bore 19 with which the block 4 is provided on one side of the bore 5. The springs 19 are held in place by a slide 20 connected with one lateral wall of the block 4. The bore 16 in tersects the key-slot 13. In Fig. 3, the key is shown partially inserted, thereby lifting the ball and innermost plunger 14 of the first device 9 and raising the plunger 17 substantially above the wall of the bore 5. In the normal position, the plungers 17 lock the key-barrel against rotation; and when the in the slot 25.

with relation to key is inserted, the balls are elevated sufiiciently to enable the barrel to rotate When the key is turned.

The device B comprises a short sleeve :21 having one ail journaled upon the reduced end 92- ot' the keyharrel and the other end joornaled on the reduced end of the rod A. The cylinder, or sleeve, 21 is provided with a pair of circumferentiaily-extending slots -24 and which are located near 0pposite ends of thh sleeve and are staggered with rehition to each other. That is to say, the slots 24 and are out tl'arongh opposite- Walls of the sleeve, and each slot prefer ably extends through somewhat more than 'a half of tl ieeireumference of the sleev The extension 5220f the hey-hsrrel is provided with a. short late al stud 26 adapted to Work; in the slot 24 o thesleeve 2i; and the extension 23 of the rod A is equipped with ashort lateral stud 27 adapted to Work The ex'tremitiesot' the slots 24- and 25 afford stops'which coaet with the studs 26 and 27.

From the foregoing description, it will be understood that the sleeve 21 may rotate the rod A somewhat more than 180", and the key-barrel may rotate with relation to the sleeve 21 through somewhat more than 180' It foi-lows that the 'keyhorret' may rotate with relation to the rod A through an angle of somewhat more than 360 the; somewhat morethan a. full rotation. 'lhis eonstrnction perl'nits the key-barrel to be returned to at given point to enable th h to be withdri f less of the. p:3'iistwhioi; the rod A may cease in the operot closing the clamping .meinhers A and upon the leaves of the ledger. ui'iderstood, therefore, serve as through the medium A It will he that the key 3 may means for turning the rod A.

of the.-key-hsrrel 6 and sleeve 21, and after the clamping members. have been ssiiiioieht-ly tightened upon the a a 1 I drawn of the leaves i I g i l l I l with len -n leaves to :rsvent their withdrawal, the key may be turned backward the point where the perforations 16 register with the perforations 19, when the key may be Withdrawn.

Inasmuch locked and 0 means of that'it will .7 a persons to open the "he hei -barrel 6 is normally e released except by it wiil be obvious "me for unauthorized binder to permit with therefrom. The son necting device joining the key-barrel to the red A a is of simple cheap and durable constrtwion. The connection between the tubular connecting member, the key- 'et-nated barrel and the threaded, scribed as a telescopic and lost/motion conneetion.

The tore "oni detailed descri tion has 1 been 5 Un tor olearness of understandin t, C)

only, hence no undue limitation is to he understood therefrom What I re ard. new, and desire to secure by Lett .7 Patei'it, is-

In lo 1" rider the combination id (thumping devices and actuating means therefor, including a right and left threaded aetuoting'rod, of a key controlled and actuated rotary member, and a tul vnlm-i count-ting member journaled on the inner and of said rotary member and the adjaeentend of said actuating rod, said tu bulsr connecting member being provided with a pair of substantially circumferential slots, and iateroily projecting pins carried by said rotary member end said rod and working in said slots, whereby the key may, after serving to actuate said clamping de-' vie-es he turned back to one point for Withdrawal regardless of the position of the Clamping devices.
